Dwyer 26110 Quarter Din Temperature Process Controller

Product Description

The DWYER 26110 is a quarter DIN temperature and process controller designed for industrial and commercial HVAC, process control, and building automation applications. It accepts a universal sensor input and operates across a wide temperature range, up to 4208 degrees F, making it suitable for demanding process environments. The controller uses fuzzy logic PID control to maintain precise setpoints and features a dual 4-digit LCD display for easy monitoring of process and setpoint values simultaneously. Powered by a 100 to 240 volt supply, the unit accommodates a broad range of electrical systems. A licensed HVAC tech or instrumentation technician typically handles installation and commissioning.

The DWYER 26110 is used in residential and commercial applications where precise temperature or process control is required, including boiler systems, industrial ovens, freeze protection systems, and HVAC air handler controls. The universal sensor input allows compatibility with multiple sensor types, reducing the need to stock sensor-specific controllers. The SSR output makes it well suited for solid-state relay-driven loads, and the built-in alarm function provides process deviation or limit alerting for critical applications.

Key Features

• Universal sensor input accepts multiple sensor types without requiring a dedicated model per sensor
• Fuzzy logic PID control algorithm for accurate, stable setpoint regulation
• Dual 4-digit LCD display shows process value and setpoint simultaneously
• Wide operating voltage range of 100 to 240 volts for flexible electrical system compatibility
• SSR output for solid-state relay-driven loads
• Built-in alarm output for process deviation or limit conditions
• Quarter DIN form factor fits standard panel cutouts

Compatibility

Designed as an OEM-style replacement or direct installation controller for quarter DIN panel cutout applications requiring universal sensor input and SSR output in temperature and process control systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or instrumentation professional familiar with low-voltage control wiring and panel-mount controllers. De-energize the control panel and verify the circuit is locked out before wiring the unit. Follow NEC guidelines for control wiring and ensure the panel enclosure rating is appropriate for the installation environment. Do not apply power until all wiring connections have been verified against the manufacturer wiring diagram.
